SETPOINTS
MAT SET
53F
38°F to 65°F;
increment by 1
SUPPLY AIR SETPOINT
Setpoint determines where the economizer will modulate the OA
damper to maintain the mixed air temperature.
LOW T LOCK
32F
-45°F to 80°F;
increment by 1
COMPRESSOR LOW TEMPERATURE LOCKOUT
Setpoint determines outdoor temperature when the mechanical
cooling cannot be turned on. Commonly referred to as the Com-
pressor lockout.
DRYBLB SET
63F
48°F to 80°F;
increment by 1
OA DRY BULB TEMPERATURE CHANGEOVER SETPOINT
Setpoint determines where the economizer will assume outdoor
air temperature is good for free cooling; e.g.; at 63
°
F unit will
economize at 62
°
F and below and not economize at 64
°
F and
above. There is a 2
°
F
deadband.
ENTH CURVE

ES1, ES2, ES3,
ES4, or ES5
ENTHALPY CHANGEOVER CURVE
Enthalpy boundary “curves” for economizing using single
enthalpy.
DCV SET

DEMAND CONTROLLED VENTILATION
Displays only if CO
2
sensor is connected. Setpoint for Demand
Control Ventilation of space. Above the setpoint, the OA damp-
ers will modulate open to bring in additional OA to maintain a
space ppm level below the setpoint.

VENTMAX L (low speed
fan) and VENTMAX H
(high speed fan) settings
are required
2.8 V

DCV MAXIMUM DAMPER POSITION
Displays only if a CO
2
sensor is connected. Used for Vbz (venti-
lation max cfm) setpoint. Displays 2 to 10 V if <3 sensors
(RA,OA, and MA). In AUTO mode dampers controlled by CFM.
100 to 9990 cfm;
increment by 10
If OA, MA, RA, and CO
2
sensors are connected and DCV CAL
ENABLE is set to AUTO mode, the OA dampers are controlled
by CFM and displays from 100 to 9990 CFM.
2 to 10 Vdc
With 2-speed fan units VENT L (low speed fan) and MIN POS H
(high speed fan) settings are required. Default for VENTMAX L

DCV MINIMUM DAMPER POSITION
Displays only if a CO
2
sensor is connected. Used for Ba (ventila-
tion min cfm) setpoint. Displays 2 to 10 V if <3 sensors (RA, OA,
and MA). Va is only set if DCV is used. This is the ventilation for
less than maximum occupancy of the space. In AUTO mode
dampers controlled by CFM.
